Hi all,
After searching for a decent compiler backend for ages (google
sometimes isn't helpful), I recently stumbled upon LLVM. Woot!!
I work on bignum arithmetic (I'm a professional mathematician) and
have recently decided to switch from developing GPL'd bignum code to
BSD licensed code. (See http://www.mpir.org/ which I contributed to
for a while - a fork of GMP).
Please bear with
